Lumps and Bumps on the Hand, Wrist and Fingers

Found a lump on your hand, wrist or finger? The common causes and what they mean: ganglion cysts, fatty lumps (lipomas), giant cell tumours, mucous cysts and carpal bossing, and when to see someone.

What you're feeling

A lump on your hand, wrist or finger is often a ganglion. That is a fluid-filled sac that grows near a joint or tendon. It can feel firm or soft, and it may change in size. Some lumps ache. Others cause no pain at all.

Where the lump sits shapes what you notice. A lump on the back of your wrist may ache when you bend your wrist back or lean on your hand to push up from a chair. A lump on the palm side of your wrist can press on nearby structures and cause discomfort with gripping. A lump in a finger, near the middle joint, can catch or block when you bend that finger, making buttons, zips and holding a pen frustrating.

The ache often flares after you use your hand. Heavy lifting, repetitive gripping or a long day of typing can make it worse. Rest usually settles it. Some people notice the lump more at night or first thing in the morning, when the hand has been still for hours.

Daily tasks can become awkward. Turning a door handle, carrying shopping bags, wringing out a washing cloth or holding a coffee cup may all pull on the lump. If the lump sits near a tendon in a finger, straightening that finger can feel stiff or slow.

Most lumps like this are harmless. Some shrink or disappear on their own, especially in children. In children under 10, ganglions are usually on the palm side of the wrist, and 69% to 79% go away by themselves within 12 to 18 months.

You do not need to rush into treatment. Watch how the lump behaves over a few weeks. Note when it aches, what makes it worse and whether it grows. That history helps your doctor work out what the lump is and what, if anything, to do about it.

What's actually happening

A ganglion starts when fluid from a nearby joint or tendon sheath (the tunnel that guides a tendon, like a pulley guides a rope) pushes out through a weak spot and collects under the skin. Think of it like a small balloon of thick, jelly-like fluid sitting on a hinge. The balloon itself is harmless, but it takes up space. That is why bending the wrist or finger can feel stiff or blocked, and why the lump may ache after you use your hand.

Where the balloon sits matters. A ganglion on the back of the wrist is close to the small bones and ligaments that let the wrist bend and twist. One on the palm side sits near nerves and blood vessels, so it can press on them as it grows. A ganglion in a finger often forms next to a tendon sheath, which is why straightening or bending that finger can catch.

Not every lump is a ganglion. Some lumps are fatty growths under the skin, which are usually soft and slow growing. Others grow from bone or from the tendon lining, and these can feel firmer. A detailed examination of the affected finger helps tell the difference between a ganglion in a tendon sheath, a trigger digit (a finger that clicks or locks) and Dupuytren's disease (a tightening of the tissue in the palm that pulls fingers toward it).

In children, these lumps behave differently. Ganglions on the hand go away more often than ganglions on the wrist, and most under-10s do well with simple watching rather than surgery.

The lump is not usually dangerous. But it can grow, press on nearby structures or keep aching, and that is when treatment becomes worth discussing.

What we can do about it

Many lumps settle without any treatment at all. If your lump is small and not painful, watching and waiting is a reasonable first step. A splint can rest an aching wrist or finger and ease the load on the lump. Gentle movement keeps the hand from stiffening while you wait. Some lumps shrink or disappear on their own, so give simple measures a fair go over a few weeks before deciding anything more.

If the lump aches, anti-inflammatory tablets or gels can calm the soreness. These are medicines that reduce swelling and pain. A cortisone injection can also settle inflammation in the tissue around the lump. For some lumps, draining the fluid with a needle is an option. This is called aspiration. It often flattens the lump quickly, though ganglions can fill up again afterwards. For a ganglion on the back of the wrist, trying at least one aspiration before considering surgery is a sensible approach.

If a lump keeps growing, keeps aching or presses on a nerve, it is worth having it assessed. Your doctor will examine the lump and may arrange scans to see what it is made of and where it sits. Some lumps are not ganglions at all. A firm lump on the back of the wrist can be a bony spur from wear-and-tear arthritis, and these are usually treated without surgery first, with splinting, anti-inflammatories and targeted injections. For a ganglion, surgery aims to remove the whole lump along with its stalk, the little duct that connects it to the joint, because leaving that connection behind makes the lump more likely to come back. Some procedures are done through small incisions using a tiny camera inside the joint, which means less cutting of the surrounding tissue.

The right option depends on what the lump is, where it sits and how much it bothers you. Bring your notes about when it aches and what makes it worse. That history, along with an examination, will help you and your doctor decide whether watching, draining, injecting or removing the lump makes the most sense for you.

What to expect

Most lumps on the hand and wrist are harmless, and many settle without treatment. Some shrink or disappear on their own, especially in children. Others stay the same size or come and go over months. If your lump aches after you use your hand, rest and simple measures often calm it down over a few weeks.

If the lump is drained with a needle, it often flattens quickly. Ganglions can fill up again afterwards, which is why trying at least one draining before surgery is a sensible approach for a lump on the back of the wrist. If surgery removes the whole lump along with its stalk, the chance of it coming back is lower. Leaving that connection behind makes recurrence more likely.

Some lumps are not ganglions. A firm lump on the back of the wrist can be a bony spur from wear-and-tear arthritis. These spurs are usually managed without surgery first, but even after surgery for them, symptoms can persist. That is worth knowing before you decide anything.

If the lump is caused by inflammation in the tendon lining, as happens with some forms of arthritis, the outlook depends on getting the underlying condition under control. Splinting can ease pain. A targeted injection into the inflamed tissue works better than tablets for a single affected area. Removing the inflamed lining can reduce pain and protect the tendons, and swelling that lasts 6 weeks or longer despite good medical treatment may be a reason to consider it.

For fatty growths and other soft tissue lumps, removing the lump completely usually settles the symptoms it caused. Some of these lumps can grow back if any tissue is left behind, so complete removal matters.

Whatever the lump turns out to be, the goal is a hand that works for the things you need it to do. Some people need no treatment at all. Others need a splint, an injection or surgery to get there. Your doctor will talk you through what the outlook looks like for your specific lump once they know what it is.

When to see someone

Most lumps are harmless, but some signs mean it is time to get checked. See your GP if a lump grows quickly, becomes painful, or changes in any way. Ask for a specialist review if a lump keeps coming back after being drained, or if it presses on a nerve and causes numbness, tingling or weakness in your fingers. Go to an emergency department if your hand becomes hot, red and swollen with spreading redness, or if you develop a fever, as these can signal an infection needing same-day care. Sudden numbness, colour change or coldness in your fingers also needs urgent assessment. If a lump feels hard and fixed in place rather than soft and mobile, ask for a specialist review so it can be identified properly.

Background & Causes

Diagnostic History and Examination

  • A careful history suggests the correct diagnosis in approximately 90% of patients with hand problems [14].
  • The patient’s hand dominance, age, gender, occupation, and hobbies requiring hand dexterity or strength should be noted during the history [14].
  • The approximate date of onset of symptoms and, if injury is the cause, the exact date and mechanism of injury should be recorded [14].
  • Patients should be questioned about prior treatment and their perception of its effectiveness [14].
  • Complaints regarding the nature of pain (sharp, aching, dull, or burning), night symptoms, aggravating and relieving factors, and timing relative to morning or end-of-day work should be detailed [14].
  • Symptoms including numbness or tingling indicate a neurologic problem rather than a mechanical one [14].
  • Specific motor difficulties, such as difficulty in writing or unscrewing jar tops, should be noted [14].
  • The medical history should include prior hand injuries and systemic diseases such as rheumatoid arthritis, diabetes, endocrine disorders, renal disease, or vascular disease [14].
  • Women of childbearing age should be questioned about recent pregnancies [14].
  • Examination of the hand should begin with observation to assess vascular condition by noting finger color and nerve function by observing sudomotor function [14].
  • The extent and timing of injury are suggested by the degree of swelling and ecymosis [14].
  • The posture of the digits and wrist may signal tendon or bone disruption [14].
  • A diagram of the hand is helpful in documenting abnormalities such as lumps, laceration sites, previous scars, amputated fingers, and areas of decreased sensation [14].
  • The hand, wrist, and forearm are gently palpated to note temperature, moisture, and areas of tenderness [14].
  • Circulation is assessed by capillary refill, where circulation should return within 3 seconds when the skin is blanched in the paronychial region [14].
  • Passive and active range of motion of the shoulder, elbow, forearm, wrist, and hand are evaluated [14].
  • The integrity of individual muscles should be documented during the examination [14].

Pediatric Ganglions

  • Pediatric ganglions can be treated expectantly, with 69% to 79% displaying spontaneous regression within a span of 12-18 months [3].

Dorsal Wrist Ganglions

  • Cystic soft tissue tumours of the dorsal aspect of the wrist have two distinct histological subtypes [7].
  • Higher postoperative pain intensity was associated with recurrence following previous surgery, treatment of the dominant hand, higher baseline pain intensity, lower credibility the patient attributes to the treatment and longer symptom duration [8].

Volar Wrist Ganglions

  • Operation-related complications after arthroscopic volar wrist ganglionectomy are associated with anatomical location distal to the bifurcation of the radial artery and concurrently penetrated up to the superficial fascia layer [33].

Other Lumps and Bumps

  • Distinguishing between a flexor sheath ganglion, trigger digit, and Dupuytren's may be accomplished with a detailed physical examination of the MCP region of the affected digit [1].
  • Giant cell tumors of the distal phalanx are extremely rare and require extensive en bloc excision to prevent local recurrence [9].
  • Digit-sparing operations may fail to eradicate all tumor foci in giant cell tumors of the distal phalanx [9].
  • An angiolipoma of the hand can be a cause of carpal tunnel syndrome [12].

Management

Diagnostic Evaluation

  • A detailed physical examination of the MCP region can distinguish between a flexor sheath ganglion, trigger digit, and Dupuytren's nodule [1].
  • Patients presenting with swelling along an affected tendon sheath, most commonly as a dorsal wrist mass, may have rheumatoid tenosynovitis, which feels irregular and diffuse compared to well-defined ganglia [18].
  • Painful dorsal wrist swelling may be the presenting symptom in rheumatoid arthritis, where tenosynovial swelling can contribute to de Quervain disease, trigger finger, or carpal tunnel syndrome [20].

Non-Operative Management

  • In children aged <10 years, ganglions mainly occur on the volar wrist and can be treated expectantly, with 69% to 79% displaying spontaneous regression within a span of 12-18 months [3].
  • Performing at least 1 aspiration before surgical excision improves the cost-effectiveness of dorsal wrist ganglion treatment, as patient preferences may preclude routinely performing 2 aspirations [2].
  • Patients who received steroids at the time of aspiration perceived lower rates of recurrence for dorsal carpal ganglions [29].
  • Conservative management in rheumatoid tenosynovitis of the hand and wrist requires rheumatologic support for systemic pharmacologic management, with splinting serving an adjunctive role to relieve pain [18].
  • Targeted corticosteroid injection into the tenosynovial inflammation is more effective than the administration of systemic corticosteroids for isolated tenosynovitis [18].
  • Scar massage is widely used by hand therapists, though few respondents had received formal skills training or completed outcome measures regularly to formally evaluate its clinical efficacy or impact [15].

Operative Management

  • Higher postoperative pain intensity following dorsal wrist ganglion excision was associated with recurrence following previous surgery, treatment of the dominant hand, higher baseline pain intensity, lower credibility the patient attributes to the treatment, and longer symptom duration [8].
  • Giant cell tumors of the distal phalanx require extensive en bloc excision to prevent local recurrence, as digit-sparing operations may fail to eradicate all tumor foci [9].
  • Both curettage and resection/amputation are acceptable treatment options for giant cell tumour of bone in the hand, with treatment decisions individualized based on site and extent of disease to minimize morbidity while maximizing disease control [30].
  • Surgical treatment for rheumatoid tenosynovitis involves removing the inflamed tenosynovium while preserving normal structures, a procedure shown to decrease pain and improve disease outcomes [18].
  • Dorsal synovectomy of the wrist may be of lasting benefit if synovitis is moderate, bone changes are absent, but pain is significant, and persistent swelling continues for 6 weeks or longer despite adequate medical treatment [20].
  • Dorsal synovectomy may be considered a prophylactic measure to avoid extensor tendon rupture in rheumatoid arthritis [20].
  • Palmar (flexor) tenosynovectomy may be useful in relieving pain and preventing tendon rupture if hypertrophy of the volar wrist tenosynovium is obvious clinically with or without symptoms of median nerve compression [20].
  • Surgical intervention for the rheumatoid wrist should be considered if the carpus is subluxated with a prominent ulna associated with local synovitis of the ulnar tendons and/or distal radioulnar joint [21].
  • The indication for rheumatoid wrist surgery is mainly based on clinical and radiographic findings, with wrist stabilization given precedence even for oligosymptomatic patients when relevant risk factors for future deterioration are present [21].

Key Considerations

Diagnosis and Differential Diagnosis

  • Awareness of anatomic variations such as a persistent median artery with a reversed palmaris longus is valuable for surgeons operating on the upper extremity [11].

Pediatric Ganglions

Dorsal Wrist Ganglion Management

  • Performing at least 1 aspiration before surgical excision improves the cost-effectiveness of dorsal wrist ganglion treatment [2].
  • Open surgery is suggested to be an ineffective way of managing cystic soft tumours of the dorsal aspect of the wrist due to high recurrence rates [7].

Rare Tumors and Masses

  • Resection followed by wrist arthrodesis and structural iliac bone graft for giant cell tumor of the distal radius achieved satisfactory oncologic and functional results [16].
  • One-third of all patients experienced some complications at a minimum of 10 years of follow-up after resection and wrist arthrodesis for giant cell tumor of the distal radius [16].

l. You means the individual or entity exercising the Licensed Rights under this Public License. Your has a corresponding meaning.

Section 2 -- Scope.

a. License grant.

1. Subject to the terms and conditions of this Public License, the Licensor hereby grants You a worldwide, royalty-free, non-sublicensable, non-exclusive, irrevocable license to exercise the Licensed Rights in the Licensed Material to:

a. reproduce and Share the Licensed Material, in whole or in part, for NonCommercial purposes only; and

b. produce, reproduce, and Share Adapted Material for NonCommercial purposes only.

2. Exceptions and Limitations. For the avoidance of doubt, where Exceptions and Limitations apply to Your use, this Public License does not apply, and You do not need to comply with its terms and conditions.

3. Term. The term of this Public License is specified in Section 6(a).

4. Media and formats; technical modifications allowed. The Licensor authorizes You to exercise the Licensed Rights in all media and formats whether now known or hereafter created, and to make technical modifications necessary to do so. The Licensor waives and/or agrees not to assert any right or authority to forbid You from making technical modifications necessary to exercise the Licensed Rights, including technical modifications necessary to circumvent Effective Technological Measures. For purposes of this Public License, simply making modifications authorized by this Section 2(a) (4) never produces Adapted Material.

5. Downstream recipients.

a. Offer from the Licensor -- Licensed Material. Every recipient of the Licensed Material automatically receives an offer from the Licensor to exercise the Licensed Rights under the terms and conditions of this Public License.

b. No downstream restrictions. You may not offer or impose any additional or different terms or conditions on, or apply any Effective Technological Measures to, the Licensed Material if doing so restricts exercise of the Licensed Rights by any recipient of the Licensed Material.

6. No endorsement. Nothing in this Public License constitutes or may be construed as permission to assert or imply that You are, or that Your use of the Licensed Material is, connected with, or sponsored, endorsed, or granted official status by, the Licensor or others designated to receive attribution as provided in Section 3(a)(1)(A)(i).

b. Other rights.

1. Moral rights, such as the right of integrity, are not licensed under this Public License, nor are publicity, privacy, and/or other similar personality rights; however, to the extent possible, the Licensor waives and/or agrees not to assert any such rights held by the Licensor to the limited extent necessary to allow You to exercise the Licensed Rights, but not otherwise.

2. Patent and trademark rights are not licensed under this Public License.

3. To the extent possible, the Licensor waives any right to collect royalties from You for the exercise of the Licensed Rights, whether directly or through a collecting society under any voluntary or waivable statutory or compulsory licensing scheme. In all other cases the Licensor expressly reserves any right to collect such royalties, including when the Licensed Material is used other than for NonCommercial purposes.

Section 3 -- License Conditions.

Your exercise of the Licensed Rights is expressly made subject to the following conditions.

a. Attribution.

1. If You Share the Licensed Material (including in modified form), You must:

a. retain the following if it is supplied by the Licensor with the Licensed Material:

i. identification of the creator(s) of the Licensed Material and any others designated to receive attribution, in any reasonable manner requested by the Licensor (including by pseudonym if designated);

ii. a copyright notice;

iii. a notice that refers to this Public License;

iv. a notice that refers to the disclaimer of warranties;

v. a URI or hyperlink to the Licensed Material to the extent reasonably practicable;

b. indicate if You modified the Licensed Material and retain an indication of any previous modifications; and

c. indicate the Licensed Material is licensed under this Public License, and include the text of, or the URI or hyperlink to, this Public License.

2. You may satisfy the conditions in Section 3(a)(1) in any reasonable manner based on the medium, means, and context in which You Share the Licensed Material. For example, it may be reasonable to satisfy the conditions by providing a URI or hyperlink to a resource that includes the required information.

3. If requested by the Licensor, You must remove any of the information required by Section 3(a)(1)(A) to the extent reasonably practicable.

4. If You Share Adapted Material You produce, the Adapter's License You apply must not prevent recipients of the Adapted Material from complying with this Public License.

Section 4 -- Sui Generis Database Rights.

Where the Licensed Rights include Sui Generis Database Rights that apply to Your use of the Licensed Material:

a. for the avoidance of doubt, Section 2(a)(1) grants You the right to extract, reuse, reproduce, and Share all or a substantial portion of the contents of the database for NonCommercial purposes only;

b. if You include all or a substantial portion of the database contents in a database in which You have Sui Generis Database Rights, then the database in which You have Sui Generis Database Rights (but not its individual contents) is Adapted Material; and

c. You must comply with the conditions in Section 3(a) if You Share all or a substantial portion of the contents of the database.

For the avoidance of doubt, this Section 4 supplements and does not replace Your obligations under this Public License where the Licensed Rights include other Copyright and Similar Rights.

Section 5 -- Disclaimer of Warranties and Limitation of Liability.

a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.

b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION, NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT, INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES, COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.

c. The disclaimer of warranties and limitation of liability provided above shall be interpreted in a manner that, to the extent possible, most closely approximates an absolute disclaimer and waiver of all liability.

Section 6 -- Term and Termination.

a. This Public License applies for the term of the Copyright and Similar Rights licensed here. However, if You fail to comply with this Public License, then Your rights under this Public License terminate automatically.

b. Where Your right to use the Licensed Material has terminated under Section 6(a), it reinstates:

1. automatically as of the date the violation is cured, provided it is cured within 30 days of Your discovery of the violation; or

2. upon express reinstatement by the Licensor.

For the avoidance of doubt, this Section 6(b) does not affect any right the Licensor may have to seek remedies for Your violations of this Public License.

c. For the avoidance of doubt, the Licensor may also offer the Licensed Material under separate terms or conditions or stop distributing the Licensed Material at any time; however, doing so will not terminate this Public License.

d. Sections 1, 5, 6, 7, and 8 survive termination of this Public License.

Section 7 -- Other Terms and Conditions.

a. The Licensor shall not be bound by any additional or different terms or conditions communicated by You unless expressly agreed.

b. Any arrangements, understandings, or agreements regarding the Licensed Material not stated herein are separate from and independent of the terms and conditions of this Public License.

Section 8 -- Interpretation.

a. For the avoidance of doubt, this Public License does not, and shall not be interpreted to, reduce, limit, restrict, or impose conditions on any use of the Licensed Material that could lawfully be made without permission under this Public License.

b. To the extent possible, if any provision of this Public License is deemed unenforceable, it shall be automatically reformed to the minimum extent necessary to make it enforceable. If the provision cannot be reformed, it shall be severed from this Public License without affecting the enforceability of the remaining terms and conditions.

c. No term or condition of this Public License will be waived and no failure to comply consented to unless expressly agreed to by the Licensor.

d. Nothing in this Public License constitutes or may be interpreted as a limitation upon, or waiver of, any privileges and immunities that apply to the Licensor or You, including from the legal processes of any jurisdiction or authority.
